3D Patchwork ruler and mat carrier

 I've been thinking about making some more 3D patch work for a while so this week I've had another play! I'm going to make a bag to carry my mat and ruler to classes!

 I know you can't tell from these photos how 3 D the patchwork works but check back in a week or two and I will show you the finish effect. I can roll the edges back just like cathedral windows to make the patchwork pieces have curved edges!
